1. Explain the relationship between a statistic and a parameter.
Answer:
A statistic is a characteristic of a sample, a portion of the target population. A parameter is a fixed, unknown numerical value, while the statistic is a known number and a variable which depends on the portion of the population.
Answer:
This is hw you do it
Step-by-step explanation:
A statistic and a parameter are very similar. They are both descriptions of groups, like “50% of dog owners prefer X Brand dog food.” The difference between a statistic and a parameter is that statistics describe a sample. A parameter describes an entire population

The perimeter of a rectangle with a length of 10 units which equation can be used to find the width of the rectangle
Answer:
2w + 20 = 55
Step-by-step explanation:
Here is the full question
The perimeter of a rectangle with a length of 10 units is 55 units. Which equation can be used to find the width, w, of the rectangle?
w + 10 = 55
w + 20 = 55
2w + 10 = 55
2w + 20 = 55
The perimeter of a rectangle's formula is = 2 ( length + breadth)
from the question ,
perimeter is 55 and length is 10
2(10 + w) = 55
20 + 2w = 55

In this problem we need to use the property of a inscribed angle:
The inscribed angle is a point in the circle that has endpoints also in the circle. The value of the inscribed angle is half the value of the arc formed by the endpoints.
So, If the arc FJ is 84°, we have that the angle in point G isi 84/2 = 42°

Write in slope intercept form.
15x − 4y = 11
Answer:
y = 15/4x - 11/4
Step-by-step explanation:
Slope-intercept form of the line 15x - 4y = 11 is y = (15/4)y + 11/4.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
We know the equation of a line in slope-intercept form is y = mx + b.
∴ 15x − 4y = 11 can be written as - 4y = - 15x + 11 ⇒ y = (15/4)y + 11/4.

All the members of a school chorus are either students or employees.The ratio of students to employees is 2:5 and the chorus has 70 members. How many employees are members of the chrous?
Answer:
50 employees are members of the chorus
Step-by-step explanation:
Total number of chorus members = 70
ratio of students to employees = 2:5
This means that if the total number of employees were to be divided into 7 parts (2 + 5), 2 parts will be students while 5 parts will be employees. Now let us convert this fraction/ratio to numbers. This is done as follows:
students to employees = 2:5
∴ employees to students = 5:2
Total parts of employees and students = 5 + 2 = 7
∴ Number of employees
[tex]= \frac{5}{7}\ of\ 70\\= \frac{5}{7} \times \frac{70}{1}\\= \frac{350}{7} = 50\ members[/tex]
∴ 50 members are employees, while the remaining 20 are students

The table shows the coordinates of trapezoid ABCD and trapezoid A'B'C'D' after a transformation.
What are the coordinates of point C?
Answer:
3,4
Step-by-step explanation:
what are the coordinates of A after reflecting across the line x = 3? (2, 3)
(3, 2) (3, 4) (3, -2)
Answer:
Here we can not see point A, so i will answer in a general way.
Let's suppose that point A is (a, b)
Now, if we do a reflection over a given line, the (perpendicular) distance between our original point to the line is the same as the distance between the reflected point and the line.
So for example if we have the point (x, y) and we do a reflection over the line x = k.
The distance between our point and the line is:
x - k
So the new point must be also at a distance of (x - k) from line x = k.
The only other point that meets this condition is (k - (x - k), y) = (2k - x, y)
Now remember that point A is (a, b)
And we do a reflection over x = 3
The distance between our point and the line is:
D = I(a - 3)I
Then the reflection will be:
(3 - (a - 3), b) = (6 - a, b)
Where (a, b) where the original coordinates of point A.

Step-by-step explanation:
The diagram shows a right-angled triangle. 37° 15 cm cm What is the value of h? Give your answer correct to 1 decimal place.
[tex]tan = \frac{opp}{adj} [/tex]
[tex] \tan(37) = \frac{opp}{15} [/tex]
[tex]h = 15 \tan(37) [/tex]
[tex]h = 11.3 \: cm[/tex]
Answer:
h ≈ 11.3 cm
Step-by-step explanation:
Using the tangent ratio in the right triangle.
tan37° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{15}[/tex] ( multiply both sides by 15 )
15 × tan37° = h , that is
h ≈ 11. 3 cm ( to 1 dec. place )
Two cars leave town at the same time and travel in opposite directions. Speed of car A is 12 km/h more than car B. They are 312km apart after 4 hours. Find the speed of each car.
Answer:
Speed of car B is 33 km/h and speed of car A is [tex]45\,\,km/h[/tex]
Step-by-step explanation:
Let speed of car B be [tex]x[/tex] km/h
Speed of car A is 12 km/h more than car B.
Therefore,
Speed of car A = [tex](12+x)[/tex] km/h
Distance = Speed × Time
Distance travelled by car A in 4 hours = [tex]4(12+x)[/tex] km = [tex](48+4x)[/tex] km
Distance travelled by car B in 4 hours = [tex]4x[/tex] km
Also, cars A and B are 312km apart after 4 hours.
[tex]48+4x+4x=312\\48+8x=312\\8x=264\\\\x=\frac{264}{8}\\\\x=33\,\,km/h[/tex]
Speed of car B is 33 km/h and speed of car A is [tex]12+x=12+33=45\,\,km/h[/tex]
